products, such as lamb patties, croquettes orthe like. 5 In forming lambpatties, for example, it has beennecessary to shape them by hand and theprocess is rather laborious and considerable time is required for. theformation of each article. When patties are formed in this manner it isdiffioult to make them of uniformshape and size. It is undesirable alsothat the food be in contact with the hands or" the persons making thepatties. I provide a molding device by means of which lamb patties orsimilar articles of food may be prepared without contact with the handsof the operator and with substantial saving in time. In addition, thecompleted articles are of uniform size'and shape and accordingly theyare more attractive in appearance. V

The molding device consists in general of a molding chamber that isadjustable to provide for difierentsizes of molded articles and it comprises also an arrangement whereby, after the material is molded, astrip or band of bacon may be placed around the molded portion of thepatty and'secured in position thereon. The patty may then be withdrawnfrom the mold in its completed form.

Thedetails of my invention will be described -in connection with theaccompanying drawing, in which Fig, 1 is a view in longitudinal sectionof a molding device; Fig. 2 is a side elevational view of the moldingdevice of Fig. 1; Fig. 3 is an end elevation as viewed from the leftFig. 2; the cover being removed; Fig. 4 is an end elevation of a moldingattachment for the device of Fig. 1; Fig, 5 is a view in longitudinalsection taken on line V-V of Fig. 4; Figs. 6 and '7 are respectivelyreduced side and end elevational views of a stufiing device forattachment to the molding device of Fig. 1; Fig. 8 is a reducedperspective view of a decorating device that is adapted to be attachedto the stufiingdevice of Figs. 6 and 7.

Referring particularly to Figs. 1, 2 and 3, the molding device of myinvention comprises a hollow cylinder I which may be of sheet-metal andis open at both ends thereof. may also be of sheet-metal and is closedat both ends thereof telescopes within the hollow cylinder I and it isslidably movable therein for the purpose of adjusting the length of amolding chamber 3 at the left as viewed'inFigs. 1 and 2.

Adjacent the left or upper end of the hollow cylinder I, as the deviceis used in practice, a

A plunger 2 which '5 Claims. (01. 107-19) sleeve 4 surrounds thecylinder I and is slidably movable relative thereto. The sleeve 5, whichis in the form of an annular band, carries two semicylindrical members 5that are connected thereto by means of hinges 6, the latter appearing inFig, 2. The members 5 are provided on their interior surfaces with aseries of grooves I for a purpose to be later described.

A flanged cover plate 8 is adapted to fit over the ends of the hingedmembers 5 when the latter are in their closed positions in which theyare illustrated in Figs. 1 and 2. The plunger 2 is provided at its lowerend with a spring latch member It! by means of which it is adapted to bedetachably secured to the cylinder I by means of a hollow or tubularmember I I having a series of notches or slots I2 therein for engagementby a hook I3 at the upper end of the member Iii. The hook I3 is alsoadapted to engage an inwardly flanged member I4 that is secured to thesleeve 4 for the purpose of detachably connecting the plunger 2 and thesleeve 4 for permitting movement of the cylinder I without disturbingthe relative positions of the plunger 2 and the sleeve 4.

The cylinder I is provided with an outwardly extending member l5 bymeans of which the cylinder I may be moved with respect to the sleeve 4and also with respect to the plunger 2 when the latter is connected tothe sleeve 4. It Will be understood that when the latch member Itconnects the plunger 2 to the cylinder I-both of these parts may bemoved together relative to the sleeve 4. p

In the operation of the molding device, it may be assumed that thematerial to be molded for the forming of lamb patties has been preparedin suitable form for molding. The plunger 2 is adjusted with respect tothe cylinder I to provide a-molding chamber, 3 of desired depth in theopen end of the cylinder I. The latch member Ill engages one of theslots !2 to retain the plunger in its adjusted position. The cover 8 isremoved and the hinged members 5 are opened by swinging them outwardlybeyond the dot-anddash lines of Fig. 2. The cylinder 1, together withthe plunger 2, is then withdrawn downwardly through the sleeve 4 untilthe top of the cylinder I is'substantially flush with the top of thesleeve 4. The material for the molded portion of the lamb patty is theninserted in the chamber provided by the open end of the cylinder I untilthe space is substantially filled. V

The cylinder I, together with the plunger 2, is then moved upwardlythrough the sleeve '3 to substantially the position shown in Figs. 1 and2.

A strip or a band of bacon is placed around the upper end of thecylinder l with the molded material inside thereof and the hingedmembers 5 are closed, the grooves 1 operating to retain the bacon inposition. The cover 8 may then be placed on the outer ends of themembers 5 and the plunger 2 is moved upwardly to cause the materialwithin the cylinder to be pressed or compacted within the upper end ofthe cylinder 1.

The latch member H! is then released and the cylinder l is withdrawndownwardly without disturbing the relative positions of the sleeve 4 andthe plunger 2. The molded material remains in its position on top of theplunger 2. The strip or band of bacon is then secured to the centralportion of the molded material of the lamb patty, as by means of smallwooden pins which may be of any suitable size or shape. This latteroperation is permitted by slots 5? in the hinged members 5. The slotsmay be of such size and shape as to readily permit the openings of themembers 5 after the pins are in position. Slots may be also provided inthe end of the cylinder l, butif the device is manipulated in the mannerdescribed herein, they are unnecessary.

When the cover 8 has been removed, the hinged members 5 are openedoutwardly beyond the positions shown by dot-and-dash lines, Fig. 2, theplunger 2 is moved upwardly relative to the cylinder l and sleeve 6 toraise the molded portion of the lamb patty on a level with the tops ofthe cylinder l and sleeve 4, whereby the completed patty may be removed.The apparatus is then adjusted for a succeeding lamb patty and theoperation described above is repeated.

The foregoing description of the operation of the molding device hasbeen given by way of example as it is obvious that the sequence ofmanipulation of the parts may be varied somewhat without affecting theresults securedthereby.

It will be noted from the foregoing that my improved molding device issimple in construction and expeditious in operation to form lamb pattiesof desired size and the product is of uniform size and appearance,inasmuch as all of the material for forming the patties may be handledby suitable implements without touching the hands.

While the principal purpose for which the molding device is provided isas described above, it is also adapted for other uses such, for example,as in molding croquettes or ice cream in novel forms by means of theapparatus shown in Figs. 4 and 5. A molding device l9, having an annularsleeve 25 for surrounding the upper end of the hollow cylinder l isconnected to the interior of the cylinder l by means of a relativelysmall aperture 21 whereby material may be forced therethrough by meansof the operation of the plunger 2. It wiil be understood that the outerend of the mold l9 may be held against a vessel or flat surface and themolded article may be readily separated from the remainder of thematerial by reason of the relatively small aperture 2| which connects itthereto. While the molding device 59 is shown of substantially pyramidalform it may have various shapes as desired.

A further adaptation of the device is in connection with the deviceshown in Figs. 6 and 7 which comprises a tubular member adapted to fitover the upper end of the cylinder l and to be fastened thereto as bymeans of a bayonet joint 24 and which is provided with a nozzle 25 ofsubstantially rectangular form which may be used, for example, inpreparing stulfed pork chops. This operation, which has been performedmanually heretofore, has always been attended with difilculties.However, by means of the device of Figs. 1 and 2, when provided with theattachment shown in Figs. 6 and '7, the stumng material may be easilyand readily forced into suitable slits or openings provided therefor inthe pork chops by inserting the nozzle therein and operating the plunger2 to force the material through the nozzle 25.

A further adaptation of the molding device is provided by the use of thedecorating device 26 shown in Fig. 8. This device, which is of suchcross-section and size as to fit upon the nozzle 25, is providedvwith aseries of spaced openings or holes 21 by means of which decoratingmaterial may be supplied to-cakes or other articles of food,

such, for example, as in providing them with chocolate .or other plasticdecorating material.

The foregoing uses for which my improved molding device is adapted aregiven by way of example only and it is'not intended to be limitedthereto except as expressed in the claims.
